forms a light, easily operatedand efficient slicing machine of the manual "feedftype, in vwhich Y the rotary knife C is rotated at relatively v'high speed vby electric motor means. The carriage H3 is guided by thel tracks H, H1, but the carriage is moved manually by the hand of the'uper` xator.

. along 'a fpathpreferably atV right angles to the cutting plane is thepusher plate J, Vwhich is Mounted on the .carriage forv movement .also manually operated. YFor example, the opervator .may grasp with his hand the sleeve J4, the .arm J3 or thehandle J1. By thrusting forwardly along the cutting plane and somewhatV inwardlytoward the, cutting lplane the work is `thrust .into effective contact with the forward face ofthe gauge plate M. -A continuation ofthe Yinclined thrust carries the carriageand the work7 properly gauged, against the cutting edge of the knife C5. The slice is cut and falls `'upon the slice receiving tray` N. .The work meanwhile continues across the face of the guard plate E until Ythev Work rhas been entirely icarried past-the cutting-edge andthe slice has, been severed. The

vorxerator then manually withdrawsthe lcarriage .and repeatsfhis inclined thrust for. the yensuing stroke and slice.

It will be noted that the carriage is mounted upon the two tracks H, H1, two sleeves H4 slidably y engaging the track H and a roller engaging the outer track H1. rotating on the pin H7, may conform readily to any slight variation in the distance' separating y 1 Y the two` tracks. This prevents any cramping or noise resulting from any slight misalignrnent of the tracks and'makes a precise positioning ofthe two tracks less important, which is a vhelpin Amanufacture and assembly. Notealso that the Acircumferential groove of the roller H6 is of different vcross-'sectional shape than the opposed face of the track H1. It may be arcuate but if 'so should be of an arc of less diameter. Inother words,'I prefer 1to`have the roller engage the trackA at two laterally spaced points rather than have itengage the track over an extended area. Ind
